How to use proxmark3 with hitag-2
I have proxmark versions:
#db# Prox/RFID mark3 RFID instrument
#db# bootrom: svn 486-unclean 2011-08-28 18:52:03
#db# os: svn 486-unclean 2011-08-28 18:52:03
#db# FPGA image built on 2009/12/ 8 at 8: 3:54
How i can emulate Hitag-2 cards?
I see hitag2.c in armsrc so as i understand firmware of my proxmark3 has ability for working with hitag-2?
But how to use it? I cant find any commands for hitag.

Re: How to use proxmark3 with hitag-2
How can I read PCF7936 chip? What antenna do I need to read car immobilizer chips? My home-made antenna doesn't react to it. Do I need to use some antenna like on this pic?

Re: How to use proxmark3 with hitag-2
After some testing I came to the conclusion that it works great if you have a smaller (focused) antenna.
What I mean is a Low Frequency (LF) antenna made from a lot of copper windings with a diameter of around 4cm.
The usb Hi-Rose cable length doesn't matter so much (in comparison to a HF antenna).
What actually worked great for me was to use the biggest (65x35mm) 125 kHz antenna from SonMicro. You need to fold the antenna once, so you will get a double circle. Welt both ends of the antenna to the RED and WHITE wire of a usb Hi-Rose cable (cut at around 25 cm length works great). This will give you a 30v antenna at 125kHz and 41v at 134kHz.
Good luck, keep us posted if you have any results from your experience 
PS. You can always look with "proxmark3>lf hitag list" if the read worked partially (reading id alone for example).
